Hi,
I am working on a plugin developed by someone. It has a perspective in
which the user is required to open a folder containing many .wav files
along with associated text and an xml with same name containing some
details of that wav file. The perspective will then show the Tabular view
in which a row contains the wav file path, a tick mark for the presence of
text and xml files. When one of the row is clicked it opens some editors
like text editor for text file and some buttons,etc for the details in xml
file.When I close and start eclipse then the Tabular view do not retain
the last selected wav files/folder state. I have read in may places that
eclipse retain the state by default, I tried to find out why it is not
retaining the state but I could not. Please help.

Thanks
Rahul

I doubt eclipse saves by default. You have to save the preferences using
IEclipsePreferences. And restore then on eclipse restart.

You might wanto read the details at

To store the preferences:

IEclipsePreferences preferences = new
InstanceScope().getNode("com.my.plugin.id"); // Get the preferences for your plugin
preferences.put("key", "value"); // store a key-value pair in it
preferences.flush(); // persist it on disk

And to retrieve

IEclipsePreferences preferences = new InstanceScope().getNode("com.my.plugin.id"); // Get the
preferences for your plugin
String value = preferences.get("key", "default value"); // retrieve the value
